ISO accidentally left at 400, lighting sub par. Sigh. Today was one of those days when I go out with a bunch of people and try to focus on finding things for them to see, or helping ID things, and end up taking very few photos. Oh well. It was fun all the same, and there were plenty of other photographers on hand. Met two more nudibranch folks, Bill (?) and Doug, who said they were collecting data and were planning a publication with Jeff Goddard. Much like the two guys I met last time at Pillar Pt (whose names I forget), these two lamented the paucity of slugs to be found relative to 10 or 20 years ago, glory days of untold abundance and disversity, apparently.

The rhinophores (left shown here) have a series of projections on the posterior side. The clavus is perfoliate, retractable, and projects from an anterior shelf. It has a crownlike ring of projections around it. Photo by Dave Cowles, August 2005

white dendronotus

The eggs are laid in gelatinous white strands, which are often attached to the tubes of their anemone prey. This nudibranch is very active, rapidly swirling its cerata around when it crawls or swims. Click here for a movie of the animal waving its cerata. The heart of this nudibranch is large and easily seen beating through the dorsal surface. Click here for a movie of the heartbeat.
